FrF2: Fractional Factorial Designs with 2-Level Factors

Regular and non-regular Fractional Factorial 2-level designs
can be created. Furthermore, analysis tools for Fractional
Factorial designs with 2-level factors are offered (main
effects and interaction plots for all factors simultaneously,
cube plot for looking at the simultaneous effects of three
factors, full or half normal plot, alias structure in a more
readable format than with the built-in function alias).
